“…Gluconobacter is supposed to be the causative agent of the pineapple pink disease (Swings and De Ley, ). Recent studies confirmed the plant‐pathogenicity of Gluconobacter cerinus CDF1 (He et al ., ), which fastens the rottening of bananas while being beneficial for the development of its transmitting fruit fly Bactrocera dorsalis . Any specific involvements of T1‐LS from Gluconobacter in plant pathogenicity or animal interactions, however, still need to be demonstrated.…”

Summary Acetic acid bacteria (AAB) are associated with plants and insects. Determinants for the targeting and occupation of these widely different environments are unknown. However, most of these natural habitats share plant‐derived sucrose, which can be metabolized by some AAB via polyfructose building levansucrases (LS) known to be involved in biofilm formation. Here, we propose two LS types (T) encoded by AAB as determinants for habitat selection, which emerged from vertical (T1) and horizontal (T2) lines of evolution and differ in their genetic organization, structural features and secretion mechanism, as well as their occurrence in proteobacteria. T1‐LS are secreted by plant‐pathogenic α‐ and γ‐proteobacteria, while T2‐LS genes are common in diazotrophic, plant‐growth‐promoting α‐, β‐ and γ‐proteobacteria. This knowledge may be exploited for a better understanding of microbial ecology, plant health and biofilm formation by sucrase‐secreting proteobacteria in eukaryotic hosts.

“…Previous studies have indicated that some plants can release more β-caryophyllene after infection by some bacteria 25–27 , and egg-surface bacteria can cause the fruit to rot 28 . Thus, we hypothesized that egg-surface bacteria are involved in increasing β-caryophyllene in fruits.…”

“…From this point of view, the increased volatile terpenoids or β-caryophyllene in bacteria-infested plants may be a defence response of plants and may contribute to inhibiting bacterial infection. Thus, it is not surprising that the increased β-caryophyllene in B. dorsalis host fruits was induced by egg-surface bacteria and demonstrated a role in host fruit defence against egg-surface bacteria since surface bacteria can cause fruit rot 28 .…”

“…This species is significantly more abundant in OFM than PFM and may contribute to the different ratios of ABC transporters and the Two-component system. Gluconobacter cerinus was another species present in PFM and OFM, which may have a beneficial role as in the case of fruit flies where it can affect reproduction (46). Pantoea is a highly diverse genus that can cause plant diseases and human diseases but also have functions in habitat restoration and pesticide degradation (47).…”

Numerous gut microbes are associated with insects, but their composition remains largely unknown for many insect groups, along with factors influencing their composition. Here, we compared gut bacterial microbiota of two co-occurring agricultural pests, the peach fruit moth (PFM) and the oriental fruit moth (OFM), collected from different orchards and host plant species. Gut microbiota of both species was mainly composed of bacteria from Proteobacteria, followed by Firmicutes. The two species shared bacteria from the genera Pseudomonas, Gluconobacter, Acetobacter, and Pantoea, although endosymbiotic Wolbachia was the most abundant genus in PFM and Lactobacillus was the most abundant in OFM. PFM tended to have lower diversity and richness of gut microbiota than OFM; however, only some of the comparisons were statistically significant. Orchards can influence gut microbiota in terms of richness, particularly for PFM, but not so much for diversity parameters. Functional prediction of gut microbiota showed that the top pathways are amino acid metabolism, translation, and membrane transport in both species, but their abundance varied between the two moth species. These results show that two fruit moths share many features of gut microbiota, and the bacterial species are relatively stable within moth species even when they use different host plants. Our study suggests that fruit-feeding behavior may play a role in shaping gut microbiota of the two fruit moths, which may provide microbial targets for pest control.ImportanceUnderstanding the associated microbes with insects can point to new targets for pest control. Here we compared bacterial community in the gut of two co-occurring agricultural pests, the peach fruit moth (PFM) and the oriental fruit moth (OFM), collected from different orchards and host plant species. We found that the bacterial genera Pseudomonas, Gluconobacter, Acetobacter, and Pantoea are abundant and shared in two moths. The composition of the bacterial species is relatively stable within moth species even when they use different host plants, indicating that the gut microbiota community in the PFM and OFM is likely to be related to their fruit-feeding behavior. The findings have implications for developing novel pest control approaches by targeting gut microbes associated with the two moths.
